==Safety==

* Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input power circuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live.

* Don’t weld lead, zinc, copper, cadmium, stainless, or beryllium. Welding these materials can be harmful if not equipped with proper safety gear and training.

* Don’t weld in wet gear or standing water because this could create a new path for the electrical current to travel and cause a severe electrical shock.

* Always turn gas and the welder off when you are done in the welding shop to ensure there are no leaks that could cause asphyxiation (suffocating from lack of oxygen).

* Never weld without a welding helmet. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld.

* Never weld without gloves. Gloves protect your hands from the heat as well as the arc rays.  

* Never weld without gloves. Gloves protect your hands from the heat as well as the arc rays. No bare skin should be exposed.

* Don't weld with the vent hood off. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. Asphyxiation can also occur due to the confined nature of the welding shop and the use of welding gasses.

* Always weld with the door open to lower the risk of asphyxiation.
